Pneumatic proximity sensors 8.7 Examples of application • Measuring the speed of transport of screens (plastic screens) for silk screen printing. These screens are easily contaminated and optical proximity sensors are therefore unsuitable. A possible solution is to provide holes at specified intervals along the edge of the screens and to use pneumatic sensor nozzles for sensing. • Monitoring of tools (e.g. checking for broken drill) in environments where for instance optical proximity sensors are unsuitable because of contamination due to oil or cooling agents. • Checking holes after drilling operation. • Testing ceramic plates for smoothness after burning. Fig. 8.7.1: Checking for broken drills by means of an air barrier By using an air barrier, it is possible to check that a drill is in position immediately before drilling the workpiece. If the drill is broken, the air jet from the se...
